Seeper Trace

Seeper Trace, the walkover pipeline integrity assessment for long-distance pipelines, is the only commercially available technology that quickly and cost-effectively locates seeps in pipelines that carry liquids, gases or multi-phase products. A seep as small as one-gallon-per-day can be detected – with no service interruption or excavation required. The pipeline is first inoculated with a small amount of tracer chemical and then the Seeper Trace instrument is “dragged” along the surface above, where it detects the presence of the tracer chemical if a leak exists.


This technology offers the flexibility of either “walking” the instrument over-the-ground above the pipeline or attaching it to a vehicle, terrain permitting, thereby making rapid results even easier to obtain. Seeper Trace service works without the insertion of probes.



Integrity Assessment of Leak Location


Operators can use Seeper Trace leak detection service for periodic pipeline integrity assessments or to locate a suspected release. Integrity assessments are particularly useful for prioritizing responses when problems are indicated by inventory discrepancies and data from smart pigging and close interval surveys. This test, when used in conjunction with pigging or hydrotesting, is particularly economical.
